Specification of Letters Patent.

Patented Oct. 22,1912.

Application filed November 2, 1911. Serial No. 658,199.

To all whom it may concern:

Be it known that I, FRANKLIN M. TATUM, a citizen of the United States, residing at Nacogdoches, in the county of Nacogdoches and State of Texas, have invented certain new and useful Improvements in Roller- Bearings, of which the following is a specifi- I cation.

This invention relates to improvements in roller bearin s.

The principal object of this invention is to provide a. pair of spaced rings, a plurality of bearing rollers disposed between and ro-' tat-ably supported by said rings, and a novelbearing for each end of each roller, whereby said rollers can revolve with a minimum amount of friction.

Another object of the invention is to provide a. roller bearing of the character described,- which is composed of a minimum number of parts, is therefore simple in construction, and is cheap to manufacture.

W' ith these and other objects in view, the

invention consists in the construction and novel combination of parts hereinafter fully ascribed, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various. changes'in the form, proportion, size and minor details of construction, within the scope of the claims, maybe resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing: Figure 1 is a longitudinal sectional view through a hub and axle showing the application of a roller bearingconlructed in accordance with my invention, Fig. 2 is a transverse sectional view taken on the line 2-2- offFig. 1, and-Fig, 8 is a,

detail end elevation'of the bearing.

Like reference numerals designate corresponding parts in all the figures of the drawin l v o ltefer'riiig' to the drawing, 5 desi ates an axle and 6 a hub both being of or inary construction.

My invention comprises a roller bea'rin adapted to be disposed between the axle and the hub and consistsof a pair of spaced rings 7- 4.

axles 8 are each connected at its ends to the rings 7.

disposed around the axle 8 between the shoulder 12'of the counterbore and the follower 14. Itwill thus be observed that by means of the springs '15, the followers 14 will be urged outwardly against the antigage with the rings 7. The springs 15 will also exert an 'inward pressure u rollers 9, and thereby tend to contra 1y positionsaid rollers. Asa result, when the rollers 9 are rotated, the friction balls 13 will and the ring 7.

It is to be noted that the diameter of the axles 8 is less than the diameter of the bores 10. As aresult, the anti-friction balls 13 not only form bearings for the rollers, but also take up any end thrust, as above described. 1 e

In order to assemble the rollers and rings the springs 15 of each roller are compressed and glued together while compressed. These springs are then positioned within the ret-hen the followers and anti-friction balls are positioned in the order named The rollers are then secured between the respective rings, after which the bearing in its entirety is boiled, whereby the glue will liquefy and cause the said springs to expand.

What is claimed is:

In aloll'er bearing, the comhinat a pair of-spaced rings, of a p spaced axles connected at their c.

11 the spectlve counterbores of the rollers, and

A plurality of spaced parallel A. plurality of anti-friction rollers 9 are each formed with a longitudinal bore posed a follower 14. A coil spring 15 is friction balls 13 and cause the latter to en-- 7 minimize the friction between the rollers I l enemas tivelyformed With longitudinal bores for receiving said axles, the diameter of each bore being greater than the diameter of therespective axle, the length of the bearing roller being less than the distance between the rings, each roller having each end formed with counterbores forming a consequent shoulder, a plurality of anti-friction balls disposed within each counterbore between the axle and the roller for supporting the latter, a disk disposed Within each counterbore and bearing against the balls and resilient means disposed between said disk and the shoulder of each counterbore to urge 15 said balls outwardly against the ring to take up the end thrust of said rollers.
